COMI S.p.A.

The thermoforming machines model BasicLine and SuperLine are a universal system suitable for the production of household refrigerator inner doors and liners, which does not need any additional adjustments: a series of in line stations make fully automatic the forming process of plastic materials in sheet (ABS and HIPS) with thickness from 0,5 to 8 mm.

LOADING
• Sheet

HEATING
• One station in BasicLine, two for SuperLine
• IR ceramic or quartz heating elements

FORMING
• Vacuum in the mould
• Positive moulds

CUTTING
• Perimetral cut by guillotine or presse

The thermoforming machines model BasicLine and SuperLine of New Generation line, are a universal system suitable for the production of household refrigerator inner doors and liners, which does not need any additional adjustments: a series of in line stations make fully automatic the forming process of plastic materials in sheet (ABS and HIPS) with thickness from 0,5 to 8 mm.
Compared with the standard line, the forming process is here obtained through the establishment of vacuum in the mould, while the bubbling stage of the material is executed by a “bell” located in the upper section of the forming station. It is possible to use 2/4 bar compressed air (Pressure Forming) inside the bell during the material’s forming process and also the Cooling System, a rapid cooling of the thermoformed part.

The thermoforming machine type HEDL is suitable to work plastic material in reel or in sheets (ABS / HIPS) with thickness from 0,8 mm to 2 mm. and is designed for inner doors of domestic refrigerators production.
The coil supply ensures a very high productivity, while a range of options make the machine particularly fast in the mould changeover and set-up: the peculiarity of the machine is due to the opportunity to cut directly into the forming station.

LOADING
• from reel to reach a very high productivity, or sheet

HEATING
• single top panel at 3 steps (reel) or 2 sandwich panels (Sheet)
• IR ceramic, quartz, or fl ash black heating elements

FORMING
• Forming by vacuum in the mould, with ballooning through a bell integrated in the mould
• Compressed air at 2/5 bar inside the bell, to support vacuum
• positive or negative moulds

CUTTING
• perimetal cut by guillotine or punching presses
• chip cutting system at exit station
